core.certmanager: Include ffdhe2048 from RFC 7919 as default DH param This removes one manual (yet undocumented) step that was supposed to be done to get a complete 'intermediate' configuration. This file can be found on the Internet by searching for "ffdhe2048" and can be verified by comparing the hexadecimal representation of p from the RFC with the output of `openssl asn1parse`. Given the preference and prevalence of ECDHE, it seems likely that few would have noticed this.

if not math.type then

	local function math_type(t)
		if type(t) == "number" then
			if t % 1 == 0 and t ~= t + 1 and t ~= t - 1 then
				return "integer"
			else
				return "float"
			end
		end
	end
	_G.math.type = math_type
end
